One of two water fountains that once graced the Plaza lawn - July 1966
I'm trying to remember when the fountains were removed.
I would guess the Iowa freezing/thawing weather eventually damaged the concrete base to where it started leaking.
Each year it had to be drained during the winter which made extra maintenance but I think it would be nice if they were replaced with some new fountains someday.
Of course with the politically correct world we live in now I'm sure the cost of liability insurance would be prohibitive for fear some unattended child would drown in it, and a barricade to prevent such an event would detract from the fountain so this idea probably will never happen.
